By what measure or observation are you determining that the blue channel is clipped?
Right, I do all processing in CaptureOne. It is "clipped" if blue channel value is 255 in the sky. Most of the time it is recoverable by adjusting color temperature, exposure, or highlights, but not always.
I do not believe a sensor has anything to do with it, it's the camera meter's job to maximize sensor capabilities for any given scene. And indeed, my Nikon cameras tend to expose at -0.5EV relative to my Sony cameras when I shoot them together on the same photoshoot. Not always, but quite frequently.
That said, this could very well be the C1 engine issue, because mapping internal 16-bit luminance values to 8-bit values you're sampling, is the RAW converter's job. I do not have an a7r6, but I noticed that C1 uses a steeper contrast curve with a7r5 files relative to Sony's own or Adobe's profile.
